Polystyrene nanoplastics induce apoptosis, autophagy, and steroidogenesis disruption in granulosa cells to reduce oocyte quality and fertility by inhibiting the PI3K/AKT pathway in female mice

Journal of Nanobiotechnology
Background Nanoplastics (NPs) are emerging pollutants that pose risks to living organisms. Recent findings have unveiled the reproductive harm caused by polystyrene nanoparticles (PS-NPs) in female animals, yet the intricate mechanism remains ...

Ovarian teratoma in the mare: a review and two cases [PDF]

, 2010
A 4-year-old Belgian Warmblood mare suffering from pelvic flexure impaction was diagnosed with a teratoma of the left ovary. The enlarged ovary was identified several days after treatment of the impaction.

Food Restriction Induces Changes in Ovarian Folliculogenesis, Cell Proliferation, Apoptosis, and Production of Regulatory Peptides in Rabbits

Animals
The aim of this study is to examine the influence of food restriction on rabbit ovarian functions. A total of eight females were fed ad libitum (NF), while eight females were subjected to 50% food restriction (RF).

Degeneration of postovulatory follicles in the Iberian sardine Sardina pilchardus: structural changes and factors affecting resorption [PDF]

, 2007
Inaccuracy in the aging of postovulatory follicles (POFs) and in estimating the effect of temperature on the resorption rate of POFs may introduce bias in the determination of the daily spawning age classes with the daily egg production method (DEPM). To

The epithelial Na+ channel (ENaC) in ovarian granulosa cells modulates Ca2+ mobilization and gonadotrophin signaling for estrogen homeostasis and female fertility

Cell Communication and Signaling
Ovarian granulosa cells are essential to gonadotrophin-regulated estrogen production, female cycle maintenance and fertility. The epithelial Na+ channel (ENaC) is associated with female fertility; however, whether and how it plays a role in ovarian cell ...

CRISPR targeting of FOXL2 c.402C>G mutation reduces malignant phenotype in granulosa tumor cells and identifies anti‐tumoral compounds

Molecular Oncology
Forkhead box L2 (FOXL2) encodes a transcription factor essential for sex determination, and ovary development and maintenance. Mutations in this gene are implicated in syndromes involving premature ovarian failure and granulosa cell tumors (GCTs).

Niemann - Pick C2 regulates steroid hormone secretion and lipid deposition in chicken follicular granulosa cells

Poultry Science
Follicular development is tightly regulated by the coordinated action of multiple hormones and complex gene regulatory networks in granulosa cells, which play a crucial role in egg production and fertility in hens. Extensive studies have established that

Interference of pseudorabies virus infection on functions of porcine granulosa cells via apoptosis modulated by MAPK signaling pathways

Virology Journal
Background Pseudorabies virus (PRV) is one of the major viral pathogens leading to reproductive disorders in swine. However, little is known about the effects of PRV infection on porcine reproductive system.
